In Episode 11 of "Liar, Liar," the Allied Army, led by Shinohara Hiroto and Saionji Sarasa, faces off against Miss Hundred Faces' United Army in the ASTRAL game. Shinohara has successfully allied with several academies, including Suisei, Ouka, Oumi, Murakumo, and Souken, bringing the total number of active players in the Allied Army to 20. In contrast, Miss Hundred Faces' United Army consists of 14 players from academies such as Seijo, Shinra, Otowa, Saint Rosalia, and Tsuyuri.

The episode consists of a series of intense battles. Saionji Sarasa leads the charge against the main unit of Miss Hundred Faces' United Army. In another area, Kirigaya Touya and Kugasaki Seiran of the United Army fight against a combined team from Suisei Academy and Souken Academy. Meanwhile, Shinohara Hiroto's Eimei Academy team collaborates with Oumi Academy to face off against Kururugi Senri's Demon Maiden team.

Shinohara Hiroto reveals a new ability called "Compound Upgrade," which allows him to combine spells to execute stronger attacks. Despite Kirigaya Touya's impressive defense, which includes an "Inability Barrier Upgrade," Hiroto manages to break through thanks to a planned betrayal by Minami Shizuku from Rosalia.

On another front, Kururugi Senri, who initially fought for Miss Hundred Faces, switches sides after a compelling conversation with Shinohara. She uses her "One-Shot Kill" ability against Miss Hundred Faces but fails to eliminate her. The episode concludes with the end of the fourth day of ASTRAL, with Seijo Academy being the team holding the most territories and receiving the most support votes.
